Reverb (short for reverberation) is the acoustic environment that surrounds a sound. Natural reverb exists everywhere. Whether the space being described is a bathroom or a gymnasium, the essential characteristics remain the same. Reverb is composed of a series of tightly-spaced echoes. The number of echoes and the way that they decay play a major role in shaping the sound that you hear. Many other factors influence the sound of a reverberant space.
Vascular calcification (VC) is a predictor of cardiovascular morbidity and mortality. Hemodialysis (HD) patients suffer from severe vascular calcifications. Matrix Gla protein (MGP) is a central calcification inhibitor of the arterial wall and its activity depends on vitamin K-dependent Î³-glutamate carboxylation. Noncarboxylated MGP, formed as a result of vitamin K deficiency, is associated with cardiovascular disease.
HLA are proteins that are located on the surface of the white blood cells and other tissues in the body. There are three general groups of HLA, they are HLA-A,HLA-B and HLA-DR. There are many different specific HLA proteins within each of these three groups.
